Ac/heat duckwork.

Hello.
I have an 84 Skyline that we just purchased.
I've discovered the jackass that installed the dryer vented it straight through the heating/ac duckwork. Now the heat goes under the home instead of towards the back half of the home .
Can I cut out the bad section which is only 8 to 10 inches and install I new piece and where can I buy a replacement.
Thanks.

Check if the existing duct is round, oval, or rectangular—this affects the replacement fit.
While you’re at it, consider installing a backdraft damper or insulation wrap, especially if the duct runs under the home.

And don't forget to add backdraft damper and wrap insulation if the pipe is located where heat loss is easy.
